1201 or less in the same spot indefinitely, food will be brought to them. And that is what happens. As a rule they do not even ad- -vance to meet their parents when they see them bringing food, even one step. Usually, also, they are pretty capable of taking care of themselves before they assimilate the fact of my being in some way hooked up with the food supply. Thus Brownie's special charge, for the first time, on the 14th., came to me with his pa- rent. Nova feeds her bird (or birds) suet extensively. Rhody continues to do all the regular things appropriate to the occasion, following out his recent trend of displaying less when given a mouse. (I.e.: less often displaying). Rough- ly, now, I should say that he goes through the ritual about half the time. He still roosts in the oak west of the house at night, uses nest 5-36 to rest in, adds a little to it now and then, re- tains his interest in the magpies, likes to preen in the cage for many minutes at a time, continues to lay unsuccessful siege to the lizard resident there, investigates the cause of disturbances amongst the other birds and inspects all new creations of mine in and about the property. About 5:30 P.M. on the 14th. I was letting the magpies reach through the wire netting for pieces of meat held in hand. Rhody, seeing a good opportunity to observe them more closely, flew up to a handy perch and sat a foot from my hand watching intently, with bulging eyes and skin colors fully displayed, crest raised. It has been noted herein that this skin is of crepe-like texture, b but that it can be stretched out smooth: "tightened up". This was very noticeable on this occasion. He did not attempt to peck either magpie, but kept his bill pointed at one or the other of them as they moved about, and "popped". He looks directly at an object in which he is intensely in- terested most of the time, although he may use first one eye and then the other, but not on this occasion. This "pop" is a single snap of the beak, not often heard. IT is not a click, but a rather resonant pop. June 15th. 1936 Gopher-snake eats mouse. Julio caught a gopher-snake at the kitchen door and caged him temporarily. This creature will be used to amuse Rhody in front of the movie camera (I hope). I gave him a live mouse. He was awkward and slow in catching it, but when he once had a grip on it, with lightning rapidity crushed it between folds of his body-- not in his "coils"--retaining his head-hold at the same time. He uses this fold as a "hand" to hold the mouse while he is try- ing to push his mouth over the mouse's head. He continues to hold the mouse in this way until it is fairly well down his gullet. From the time he got his first teeth on the mouse until it was about one foot on the way down, about 15 minutes elapsed. Rhody as usual all day, including adding to nest 5-36. Length of Rhody. When he stretched out in one of his spread-eagle summing poses by my chair in which he lies flat on his belly, with tail, neck and bill all flat on the ground and in a straight line, I marked his two extremities with matches stuck in the ground. When he got up, the interval was measured and proved to be 24 3/4 inches (628 mm.). (Hoffmann: 20 to 24; Pearson in "Birds of America: 20 to 24; Dawson: 21 to 25. Rhody, then, would appear to be above the average and near the upper limit).
